"Wait for the LORD; be strong, and let your heart take courage; wait for the LORD!" Psalm 27:14

The word "wait" means "trust". We trust in things unseen. Sometimes those things will be revealed to us at a later time and thus, we need to wait. We trust and so we wait. If we truly trust in God, we will be patient and wait for as long as it takes, because we know he will follow through on what he promises.
